Water Pump Leak - Carina E

[Carina Chris]

March 1997 Toyota Carina E 1.8GS Hatchback with 7AFE engine (73,000 miles)

The radiator has been weeping coolant for a number of years - nothing serious - but getting slightly worse now. So I've purchased a replacement radiator ready to swap out. However, today I've noticed that the floor pan directly below the water pump is wet with red coolant (rather more than what's weeping out of the rad)! Looks like I need to do both at the same time. The cam belt was replaced at 60,000 miles. Replacing the rad looks straight forward but the pump looks more fiddly. Any tips before I attempt?

Engine temp is fine and pump works well, so what has failed in the pump to cause the leak? I've always had the correct mixture of coolant so no rust coloured water, just normal pink coloured.

Is a pump refurb recommended or just a new replacement? Where can I get a good quality pump apart from Toyota who may want to charge the earth?!
